摘要 |
A transmission ratio selector mechanism for a transmission having a multi-ratio main change speed gear X and a range change gear set Y in series. The selector mechanism includes a gear lever 120 which is movable in a number of planes for the selection of the operative ratio (1,2,3,4) of the main change speed gear X and also has a plane of movement (n) corresponding to a neutral condition (NE) of the main change speed gear. The gear lever 120 is also movable whilst in the neutral plane (n) to a range change position (H/L) to affect a change in the operative range of the transmission . Each movement of the gear lever (120) to the range change position operates switch means (144) which operates a solenoid-controlled fluid-flow control valve which controls the supply of pressurised fluid to a fluid-pressure-operated range change actuator (114,115). |
